Method, system, and computer program product for controlling stereo glasses

Abstract

A method, system, and computer program product are provided for controlling stereo glasses. Left and right eye shutters of stereo glasses are controlled to switch between closed and open orientations and simultaneously remain in a fast switching orientation for a predetermined amount of time between the closed and open orientations. The fast switching orientation of each of the left and right eye shutters has at least one open time and at least one closed time. A duration from a first one of the at least one open time and the at least one closed time through a last one of the at least one open time and at least one closed time is equal to the predetermined mount of time. Each of the at least one open time of the fast switching orientation of each of the left and right eye shutters is shorter than or equal to 1 / 24 seconds.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to video displays and, more particularly, to a method, a system, and a computer program product for controlling stereo glasses.[0002]Due to the upsurge of 3D movies and mature development of 3D displays, 3D images, which could only be seen in theatres in the past, can now be watched at homes.[0003]FIG. 1 shows a conventional timing for enhancing a viewing experience when display content is viewed utilizing stereo glasses. A first left image L1 intended for viewing only by a left eye is sent by over a communication medium 11 first. Thereafter, there is a pause, namely, the vertical blanking interval (VBI) 12. Next, a first right image R1 intended for only the right eye is then sent, and so forth. An example of such a conventional timing is shown in U.S. Pat. No. 7,724,211 B2.[0004]The right eye shutter and the left eye shutter of the stereo glasses are controlled independently. A right eye control signal 13 can be utilize...

AI Technical Summary

Benefits of technology

[0008]An objective of the present invention is to control each of the right eye shutter and the left eye shutter to include a fast switching orientation between a closed orientation and an open position. The fast switching orientation of each of the right eye shutter and the left eye shutter includes at least one open time and at least one closed time, wherein a duration between a first one of the at least one open time and a last one of the at least one closed time is equal to a predetermined amount of time, and each of the at least one open time of the fast switching orientation is shorter than or equal to 1 / 24 seconds. Thus, there will be no visual persistence, avoiding the left eye and the right eye from perceiving the content during the overwriting procedures. Furthermore, the visual sensitization of the eyes can be increased while reducing the visual contrast during switching between the open orientation and the closed orientation. Thus, eyestrain is relieved, and the pixel saturation and color saturation are increased.

Problems solved by technology

However, in this controlling method, each of the right eye shutter and the left eye shutter in the closed orientation and during the predetermined amount of time 16, 17 cannot perceive any light, such that a strong contrast of brightness and darkness occurs when the right eye shutter and the left eye shutter switches between the closed orientation and the open orientation, and eyestrain occurs easily.

It is, thus, an important issue in this industry to solve the above problem.
